Answer:
B) 131°
Step-by-step explanation:
-4a + 139 = 4a + 123 because they are vertical angles
-4a + 139 = 4a + 123
reduce:
8a = 16
a = 2
4(2) + 123 = 131°
The area of a square is expressed as:
Area = s^2
We are given the area of both windows. We will use this value for the calculations. We set s as the side of the larger window and a for the smaller window.
Total area = Area larger + area smaller
1025 = s^2 + a^2
Since it was said that the side of the larger window, s is 5 in longer than the side of the smaller window, a (s = 5+a) then:
<span>1025 = s^2 + a^2
</span>1025 = (5+a)^2 + a^2
simplifying we obtain,
a = 20 inches
Answer:
The number x = 3
Step-by-step explanation:
Let 'x ' be the positive integer
Given data If the sum of five times a number and two times the same number and the same number is increased by 4 and the result is 25
sum of five times a number is 5 x and same number two times is 2 x and increased by 4 (addition) then result is equal to 25
so finally 5 x +2 x +4 = 25
7 x + 4 = 25
subtracting '4' on both sides , we get

7 x = 21
dividing '7' on both sides, we get


Therefore the number is x = 3
<u>Verification :</u>-
5 x +2 x +4 = 25
substitute x = 3 in above equation
15+6+4 = 25
25 =25
<u>Final answer</u> :-
The number is 3
